Can't catch SSLException - Java

Question

I am trying to parse some url's with Jsoup but I get this error:

javax.net.ssl.SSLException: Received fatal alert: protocol_version
at sun.security.ssl.Alerts.getSSLException(Alerts.java:208)

here is my code:

public Elements getLinks(String link){
    Document doc = null;
    try {
        doc = Jsoup.connect(link)
                 .userAgent("Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:25.0) Gecko/20100101 Firefox/25.0")
                 .referrer("http://www.google.com") 
                 .timeout(5000) //it's in milliseconds, so this means 5 seconds.              
                 .get();
    }  
    catch (SSLException e) {

        e.printStackTrace();
    }
    catch (IOException e) {
        if(e.getCause() instanceof SocketTimeoutException) {
            try {
                throw new SocketTimeoutException();
            } catch (SocketTimeoutException e1) {
                // TODO Auto-generated catch block
                e1.printStackTrace();
            }
   }
        e.printStackTrace();
    }

    Elements links = doc.select("a[href]");

    return links;
}

I have a catch section for the SSLException but my program stops. I don't care to parse the specific url, I just want my program not to crash. Any ideas how to fix this problem?

Well, you have the stacktrace so your catch worked and did what you wanted it to do (to print the stacktrace). As for the exception itself, there's a [question](http://stackoverflow.com/questions/16541627/javax-net-ssl-sslexception-received-fatal-alert-protocol-version) addressing what the error is saying about your code — Alfabravo, Dec 15 '15 at 20:03

As the exception is beeing thrown during the initialization of

Document doc;

this line

Elements links = doc.select("a[href]");

will probably throw some other exception that you are not catching, or the returned value will not be correctly initialized
